但是当我尝试使用ansible ping服务器时，我得到：

ssh -i "keypair.pem" ec2-user@some-ip.eu-west-1.compute.amazonaws.com

我正在使用以下主机文件：

testserver | UNREACHABLE! => {
    "changed": false,
    "msg": "Failed to connect to the host via ssh.",
    "unreachable": true
}

并运行以下命令来运行ansible：

testserver ansible_ssh_host=some-ip.eu-west-1.compute.amazonaws.com ansible_ssh_user=ec2-user ansible_ssh_private_key_file=/Users/me/playbook/key-pair.pem

输出结果为：

ansible testserver -i hosts -m ping -vvvvv

我做错了什么？

试试这个解决方案它对我来说很好用

ansible ipaddress  -m ping  -i inventory -u ec2-user

其中inventory是主机文件名。

inventory :    
[host]
xx.xx.xx.xx
[host:vars]
ansible_user=ec2-user
ansible_ssh_private_key_file=/location of your pem file/filename.pem

我遇到了问题，因为我没有给出我所指的主机文件的位置。

我遇到了类似的问题，通过Troubleshooting Connecting to Your Instance阅读帮助了我。具体来说，我正在从Amazon-Linux实例ping一个Ubuntu实例，但忘记更改连接用户名来自＆＃34; ec2-user＆＃34;到＆＃34; ubuntu＆＃34;！

您必须更改hosts文件并确保您拥有正确的用户名

    test2 ansible_ssh_host=something.something.eu-west-1.compute.amazonaws.com ansible_ssh_user=theUser

'test2' - 是我在本地ansible主机文件中给ssh machice的名称

'ansible_ssh_host = something.something.eu-west-1.compute.amazonaws.com' - 这是与ec2实例的连接

'ansible_ssh_user = theUser' - 实例的用户。 （重要）

  1. 'ssh'进入您的实例
  2. [theUser @ Instance：]确保将'theUser'复制到主机中并作为'ansible_ssh_user'变量放置

    3. 然后尝试ping它。

    如果这不起作用，请检查您是否拥有启用amazon aws的ICMP包装的权利。

这是我的主机文件的样子。 [apache] 是我们要在其上安装apache服务器的主机组。 ansible_ssh_private_key_file 应该是下载的.pem文件的路径，以访问您的实例。就我而言，这两个实例具有相同的凭据。

[apache]
50.112.133.205 ansible_ssh_user=ubuntu
54.202.7.87 ansible_ssh_user=ubuntu
[apache:vars]
ansible_user=ubuntu
ansible_ssh_private_key_file=/home/hashimyousaf/Desktop/hashim_key_oregon.pem
